and 78 machine guns. In total the Romanian command committed some 39,000 men to the battle. Early in the morning on 5 September the Bulgarian heavy artillery began an artillery barrage designed to severely damage the Romanian fortifications and earthworks. The infantry attack followed soon after with the main blow delivered by the 4th Preslav Division. By nightfall the entire first Romanian defensive line was captured and 13 out of 15 forts had fallen in Bulgarian hands. The defenders had to retreat to their secondary defensive line which was considerably weaker and fell relatively easy on the next day despite the arrival of fresh reinforcements. On that day the Bulgarian 3/1 Brigade intercepted and defeated at the village of Sarsanlar a brigade of the Romanian 9th Division consisting of 9 battalions, 4 batteries and 2 squadrons dispatched from Silistra to aid the Tutrakan garrison. When the Battle of Tutrakan ended on 6 September two Romanian infantry divisions were practically destroyed – some 28,500 soldiers and officers along with over 100 cannons, 62 machine guns and thousands of rifles were captured by the Bulgarian Third Army.

Despite the sizable forces of 46 infantry battalions, 17 batteries and 19 squadrons, General Zayonchkovsky achieved little success. The Bulgarian Varna Mobile Reserve, 6th Infantry Division managed to hold their line for two days when on 7 September the first Ottoman troops – the 75th Regiment of the 25th Division arrived and was at once dispatched to support the Bulgarians. The 1st Cavalry Division delivered a flanking attack against the Serbo–Croatian Division which caused its retreat and made the position of the rest of the Russian forces untenable. By nightfall all of the XLVII Corps and the 19th Division were in full retreat and rallied around the village of Cara-Omer further to the north. after the battle all the Bulgarian and Ottoman forces were
